To ill an A/C system correctly, you need a manifold gauge set so you can see the pressures in the system, to me it sounds like you added too much, and the relief valve opened and vented the R-134a to the atomsphere. This also sounds like the compressor has gone out or the system is low on charge or a fuse is bad, these videos and guides can help us fix the problem with diagrams below to show you how on your car. I have included (below) the air conditioner wiring diagrams as well so you can see how the system works.

It was the high pressure valve on the compressor, I got a new one and installed it to fix the problem. Thanks for the guides.
